Description
Gigabyte A520M K V2 Micro-ATX AM4 Motherboard – 2× DDR4, PCIe 3.0 x4 M.2, GbE LAN, HDMI 4K@60 + D-Sub
Summary: The Gigabyte A520M K V2 is a compact micro-ATX motherboard for AMD AM4 CPUs, supporting Ryzen 3000/3000G, 4000G, 5000 and 5000G series processors. It delivers modern essentials for value builds: 2× DDR4 slots (up to 64GB), a PCIe Gen3 x4 M.2 (NVMe) slot for fast SSDs, 4× SATA 6Gb/s (RAID supported), Gigabit LAN, and flexible display outputs including HDMI up to 4K@60 and D-Sub (VGA) for older monitors.
Build a reliable AM4 PC for home, office, or entry-level gaming with the Gigabyte A520M K V2. It’s a smart pick when you want a small, affordable motherboard that still supports fast NVMe storage, plenty of USB, and a full-length PCIe slot for a dedicated graphics card—while also keeping HDMI/VGA available for APU builds and multi-display setups.
Key features
- Socket / chipset: AM4 + AMD A520
- CPU support: Ryzen 5000/5000G, 4000G, 3000/3000G series
- Memory: 2× DDR4 DIMM, dual-channel, up to 64GB; supports XMP and high OC speeds (up to DDR4 5100 OC listed)
- Expansion: 1× PCIe 3.0 x16 + 1× PCIe 3.0 x1
- Storage: 1× M.2 (Socket 3, M-Key, 2280) with PCIe 3.0 x4/x2 NVMe + SATA support, plus 4× SATA 6Gb/s (RAID 0/1/10)
- Networking: Realtek Gigabit LAN
- Audio: Realtek HD audio (supports multi-channel output)
Rear I/O
- Video outputs: 1× HDMI (up to 4096×2160 @ 60Hz), 1× D-Sub (up to 1920×1200 @ 60Hz)
- USB: 4× USB 3.2 Gen1 + 2× USB 2.0
- Other: RJ-45 LAN, 3× audio jacks, PS/2 combo port
Build notes
- HDMI/D-Sub work only with an APU: the motherboard’s display ports require a Ryzen “G-Series” CPU with integrated graphics. If you use a standard Ryzen CPU without iGPU, you’ll need a graphics card.
- No built-in Wi-Fi: add a PCIe Wi-Fi card or USB adapter if you need wireless.
- Micro-ATX size: ideal for compact cases while still supporting full-size GPUs (case clearance permitting).
Great for: budget AM4 gaming builds, home/office PCs, upgrades from older AM4 boards, or APU builds needing HDMI + VGA support.

FAQ: Frequently Asked Questions
Gigabyte A520M K V2 FAQ
The Gigabyte A520M K V2 is a budget-friendly AMD AM4 micro-ATX motherboard designed for home PCs, office systems, and value-focused gaming builds. Below are the most common questions buyers ask before choosing this motherboard.
1. What CPUs are compatible with the Gigabyte A520M K V2?
The Gigabyte A520M K V2 supports AMD Ryzen 5000 Series, Ryzen 5000 G-Series, Ryzen 4000 G-Series, Ryzen 3000, and Ryzen 3000 G-Series processors on the AM4 socket.
2. Does the Gigabyte A520M K V2 support Ryzen 5000 processors?
Yes. Gigabyte officially lists Ryzen 5000 Series support for the A520M K V2, which is one of the main reasons buyers choose it for a low-cost AM4 build.
3. Does the Gigabyte A520M K V2 support Ryzen 5000G APUs?
Yes. Gigabyte lists Ryzen 5000 G-Series support as well. Buyers using a G-Series APU should still check the board BIOS version before ordering, especially on older stock.
4. Do I need a BIOS update for some Ryzen 5000 CPUs on the Gigabyte A520M K V2?
Possibly. This is one of the most common buyer questions in community threads. Support can depend on the BIOS version already installed on the board, so checking the CPU support page or buying from a seller with recent stock is a sensible step.
5. Does the Gigabyte A520M K V2 support older Ryzen 1000 or 2000 CPUs?
Buyers should not assume that it does. Gigabyte’s official support information focuses on Ryzen 3000 and newer supported processor families for this model.
6. How much RAM does the Gigabyte A520M K V2 support?
The board has 2 DDR4 memory slots and supports dual-channel DDR4 memory. Because it only has 2 DIMM slots, buyers planning future upgrades should think carefully about starting capacity.
7. Is ECC memory supported on the Gigabyte A520M K V2?
Gigabyte lists support for both ECC and non-ECC unbuffered DDR4 memory, depending on the processor and configuration.
8. Is the Gigabyte A520M K V2 good for a budget gaming PC?
Yes. It is a sensible option for a value gaming build with a suitable Ryzen processor and dedicated graphics card. Community discussions commonly describe it as a basic but workable AM4 board when cost matters more than premium extras.
9. Is the Gigabyte A520M K V2 suitable for high-end Ryzen CPUs?
It is better suited to entry-level and mainstream builds than to more demanding upgrade-focused systems. Buyers planning higher-end AM4 builds often compare it with stronger B550 alternatives.
10. Does the Gigabyte A520M K V2 have an M.2 slot?
Yes. Gigabyte lists 1 M.2 socket supporting PCIe Gen3 x4 and SATA mode SSDs.
11. Does the Gigabyte A520M K V2 support NVMe SSDs?
Yes. The M.2 slot supports PCIe Gen3 x4 NVMe drives.
12. Does the Gigabyte A520M K V2 support SATA M.2 SSDs as well as NVMe?
Yes. Gigabyte specifically states that the M.2 slot supports both PCIe NVMe and SATA mode SSDs, which is useful because not every budget motherboard supports both types in the same slot.
13. Does the Gigabyte A520M K V2 have built-in Wi-Fi?
No. Gigabyte lists GbE LAN, but there is no built-in Wi-Fi on this motherboard. Buyers who need wireless networking would usually add a USB Wi-Fi adapter or PCIe Wi-Fi card.
14. Does the Gigabyte A520M K V2 have onboard video outputs?
Yes. The board includes D-Sub and HDMI outputs. These are intended for use with supported AMD Ryzen G-Series processors that include integrated graphics.
15. Will the video ports work with a Ryzen CPU that has no integrated graphics?
No. This is one of the most common buyer misunderstandings. If you use a Ryzen processor without integrated graphics, you will need a dedicated graphics card for display output.
16. Does the Gigabyte A520M K V2 support multiple displays?
Yes, Gigabyte highlights rear HDMI and D-Sub for multi-display support, but this depends on using a compatible processor with integrated graphics.
17. What expansion slots does the Gigabyte A520M K V2 have?
The board includes a main PCIe slot for a graphics card and a smaller PCIe slot for additional expansion, making it practical for basic AM4 builds.
18. Does the Gigabyte A520M K V2 have HDMI?
Yes. HDMI is included on the rear I/O, alongside D-Sub.
19. Is the Gigabyte A520M K V2 good for office, school, and home PCs?
Yes. Its micro-ATX size, M.2 storage support, Gigabit LAN, and display outputs for APUs make it a practical choice for home, office, and school computers.
20. Who is the Gigabyte A520M K V2 best for?
This motherboard is best for buyers who want an affordable AM4 micro-ATX board for a sensible Ryzen build, whether for office work, everyday computing, or a budget gaming PC with essential features like HDMI, M.2 storage, and Gigabit LAN.
